Statistics - Verbal Hypothesis

(A) Research Problem:

Are students spending less time in studies now (in 2009) than they did in 2002?

Hypotheses:

(Verbal)

H0: The modal number of hours students spend on studying has remained the same (has not declined) in 2009 as

compared to 2002.

Ha: The modal number of hours students spend on studying has declined in 2009 as compared to 2002

(Numerical)

H0: Mode2009 - Mode2002 = 0

Ha: Mode2009 - Mode2002 < 0

(B) Research Problem:

Are males spending less time in studies now (in 2009) than they did in 2002 as compared to females now (in 2009) than

they did in 2002?

Hypotheses:

(Verbal)

H0: The modal number of study hours has declined by the same amount in 2009 as compared to 2002 in case of both

males and females

Ha: Males are spending less time in studies now (in 2009) than they did in 2002 as compared to females now (in 2009) than

they did in 2002

(Numerical)

H0: (ModeMales2009 - ModeMales2002) = (ModeFemales2009 - ModeFemales2002)

Ha: (ModeMales2009 - ModeMales2002) < (ModeFemales2009 - ModeFemales2002)
